  • perforated surfaces are more susceptible to contamination and damage.
  • a fastening device with which an optical waveguide at an edge region of a vehicle seat or an instrument panel or vehicle door is fastened.
  • the fastening device is a strip of material which forms a hollow part, in which the optical waveguide is guided.
  • the material strip may be a woven fabric or a fiber braid or a transparent foil.
  • a backlit footboard comprising a support plate made of a translucent material. Lettering and a desired coloring are achieved by a layer structure formed beneath the carrier plate with two opaque layers having the lettering and a color layer.
  • the light sources used to generate light effects are preferably light guides or light foils, and must be protected from damage.
  • the materials used to cover the bulbs should meet the requirements for cover materials in the vehicle interior.
  • the properties of a cover material for use in the automotive interior include, for example, a high scratch resistance, high wear resistance, low soiling and good cleaning behavior, and low crenation and low emissions.

  • coverings that are suitable for the vehicle interior such as leatherette for the automotive interior, fundamentally differ in their properties of plastic films, which are designed for example for the covering of equipment or for windows in tents.
  • plastic films are for example from the document DE 1 945 222 U known, which shows a plastic film of a clear PVC, in which a pigmented textile structure is embedded.

  • Under visible light is understood to mean electromagnetic radiation having a wavelength in the range of 450 nm to 800 nm.
  • the translucency relates to the amount of light that passes transversely through the artificial leather, ie from the back of the artificial leather (the textile substrate) to the visible side (the surface finish).
  • the invention is based on the idea to make the material of artificial leather translucent and thus to achieve new lighting options. If a translucent artificial leather is illuminated from the back, it seems to shine for the viewer on its own. This is an innovative effect that is not expected from a leather-like fabric.
  • the layer structure of artificial leather itself is transparent, ie translucent, designed. Translucent materials are used for the layer structure.
  • the layers are formed on the basis of polyurethane or polyvinyl chloride, which give a clear or milky cloudy layer from home.

For example, it depends on the thickness, number and type of layers in the layer structure, the dye content or color pigment content in the individual layers, as well as the type and density of the textile support material. To achieve the desired light transmission, the proportion is preferably adjusted accordingly to color pigments or dyes in the starting material.
  • the innovative effect of having the imitation leather look like a self-shining leather in backlighting can also be achieved with lower light transmittance in the range of 0.4% to 30% and 0.4% to 10%, respectively.
  • the artificial leather can be produced using conventional processes for the production and processing of artificial leather.
  • no additional production steps are necessary to achieve the light transmission.
  • a perforation of the layer structure or individual layers is not necessary to achieve the light transmission. Rather, the layer or layers of the layer structure are preferably formed without interruption.

  • the textile substrate may be made, for example, from natural materials, e.g. cotton, or man-made fibers of natural and synthetic raw materials, e.g. Polyamide, polyester, or glass fibers, but also be formed from mixed forms of both materials.
  • the translucent layer structure may have one or more individual layers arranged one above the other. Compact layers as well as foamed layers can be contained in the layer structure.

  • the layers of the layer structure may be formed of different materials, for example, a compact PVC layer may be formed over a foamed PUR layer.
  • the layer or layers of the layer structure may contain other ingredients such as plasticizers, accelerators, crosslinkers, UV light stabilizers or other additives.
  • the surface finish serves to protect the artificial leather from chemical agents, physical damage, e.g. Scratches or abrasion, and UV radiation.
  • the surface finish can further reduce the surface adhesion of the artificial leather.

  • the surface coating is preferably formed continuously over the layer structure and covers it completely.
  • the surface coating is formed from at least one lacquer layer, but may be formed from a plurality of lacquer layers, preferably it is formed from one to four lacquer layers.
  • the layer structure consists of one or more compact layers.
  • two or more compact layers may be formed one above the other.

  • constructing the artificial leather exclusively from compact layers can advantageously be dispensed with the use of propellants, such as ADCA (azodicarbonamide) or other substances that are considered hazardous to health.
  • ADCA azodicarbonamide
  • the light transmission of the layer structure is heavily dependent on any changes in thickness of the layer.
  • a particularly natural daylight appearance of artificial leather is achieved in one embodiment of the invention, in which the artificial leather viewed in incident light from the visible side appears opaque. It should be considered as opaque if the textile substrate is not visible when looking at the visible side of the imitation leather.
  • the desired optical effect of the artificial leather can be achieved by e.g. the coloring, the amount of dye or pigment and the number, type and thickness of the layers in the layer structure or the type of surface finish are matched accordingly.

  • the artificial leather backlit so there is a special innovative effect, since the previously seemingly opaque artificial leather shines unexpectedly.
  • the light transmittance of the artificial leather is preferably in the range of 0.4% to 30%.
  • a special optical effect can be achieved in a further embodiment in which a structure of the textile carrier material seen from the visible side of the artificial leather is recognizable when the material is backlit from the back. Without backlight, the structure of the visible side is not visible, the artificial leather acts like a conventional artificial leather. When backlighting, however, the structure of the support material visually comes into effect.
  • the carrier material has a coarse knit or weave structure or other structure.
